Puncturella chasteri was a name conferred by Mr. Jordan on an 

 immature example of P. noacJiina. 



Emarginula fissura L. — A variety of this shell, from Guernsey, 

 compressed at the sides, is analogous to Puncturella noachitia var. 

 princeps. 



E. rosea Bell. — Recorded from Whiting Bay, Clyde,^ but the 

 identification is more than doubtful. 



E. crassa J. Sow. — S.W. Ireland (R.LA. cruise). 



Li reference to my record of a specimen of E. elongata Costa, from 

 Herm Island,' it may be noted that Emarginula abounds on the 

 Herm beach in a bleached and worn condition, among which this 

 species could easily be overlooked ; but if some of the debris was 

 searched with special reference to this shell, I think more specimens 

 would be found. E. elongata is a most unlikely species to be used 

 in ornamental shell work, or by any other means to stray to this little 

 island, and, therefore, its presence on the Herm beach, in my opinion, 

 is strong prima facie evidence of its existence in the district. I have 

 not paid another collecting visit to Herm since I found this one 

 specimen. 



E. cancellata Phil, should be expunged from the British list. A 

 final search which I have made in the Guernsey Museum after the 

 discoverer's (GalHenne's) collection had been laid out, has again failed 

 to reveal the existence ot these specimens. 



A living and a dead specimen of Crepidula fornicata L., attached to 

 a Eusus antiguiis, have been recorded from the beach at Sandwich by 

 Mr. Cooper ; also from Cleethorpes by Mr. Gyngell ; and from the 

 Medway by Mr, Sikes. 



Judging from various specimens of C. unguiforniis Lam., occasion- 

 ally sent me from the River Crouch, in Essex, during the past few 

 years, it would appear that the species is destined to become natural- 

 ized in this country, together with Ostrea angiilata Lam., which 

 also seems to have become fairly established ; but careful observation 

 is required to ascertain whether these species breed in our waters be- 

 fore we can claim them as British. Specimens of both species are fre- 

 quently dredged in the Salcombe estuary, in South Devon, the results 

 of an importation many years ago ; but they are always dead, showing 

 that in this instance at least the conditions were not favourable to 

 their propagation,
